APPARATUS FOR PRESSING BRICK.

SPECIFICATION forming part of Letters Patent No. 573,514, dated December 22, 1896. Application filed February 3, 1896. Serial No. 577,949. (No model.) Patented in England March 26,1895, No. 6.239.

To all whom it may concern.-

Be it known that we, RALPH TOWNSEND llUGHEs,residing at Saltburn-by-the-Sea, and JOHN GILL, residing at Leeds, in the county of York, England, subjects of the Queen of Great Britain, have invented new and useful Improvements in Methods of and Apparatus or Machinery for Pressing Bricks, Tiles, and the Like, (for which we have obtained a patent in Great Britain, No. 6,239, dated March 26, 1895,) of which the following is a specification.

Our invention relates to improvements in the method of and in apparatus or machinery for pressing bricks, tiles, and the like.

The object of our invention is to press bricks, tiles, and the like upon the sides, or in a horizontal direction, and not downward, or in a vertical direction, as heretofore, so as to prevent the formation of arris upon the edges of same and to press them all to the same or one uniform thickness.

Figure 1 is a front elevation of our invention as operated by hand-power. Fig. 2 is an end elevation. Fig. 3 is a plan. Fig. 4 is a front elevation of our invention as operated by steam-power. Fig. 5 is a plan of Fig. l. Fig. 6 is a front elevation of automatic arrangement for opening and closing the ends of the molds. Fig. 7 is a side elevation of Fig. 6. Figs. 8 to 11 may be termed diagrammatic views. Fig. 8 is a sectional end elevation of ordinary press-box with plunger. Fig. 9 is a plan. Fig. 10 is 'a sectional end elevation of our improved press-box with plungers or presser-blocks. Fig. 11 is a sectional plan of same.

According to our invention we employ one or more molds or boxes A, preferably fixed or stationary between presser-blocks B for obtaining the side or necessary pressing action Instead of the said molds or boxes A being fixed or stationary they may be arranged so as to be capable of being moved by hand or automatically in turn between the said presser blocks for obtaining the side or necessary pressing action and afterward moved away for discharging the pressed material by hand or automatically. The said presser-blocks B are operated by cranks and toggle mechanism or by levers and toggle mechanism from shafts mounted in themaehine-frame, or by the equivalents of such. In Figs. 1 to 3 the said presser-blocks B are operated by levers and toggle mechanism and in Figs. 4 and 5 by cranks and toggle mechanism. I

In Figs. 1 to 3 the presser-blocks B are joined to links 13', centered at B to arms or levers B which are joined to links 13, which are joined to the axis or shaft B at both sides. (See Fig. 1.) The arms or levers B are pivoted in bearings l5 at the top end.

hen it is desired to have the panels deep 011 one side and shallow on the other, this is eifected by making one of the levers 13 long and the other one short, so that there is a variation in the depth of the pressing action. The said molds or boxes A are made, preferably, in one piece or casting with a solid top A and solid bottom A with apertures in one or both sides for resser-blocks B to work through. The said molds or boxes A may be made in sections or segments jointed together or with removable liners for different sizes of bricks. The said molds or boxes A are provided or constructed with open ends, adapted to fit into which are slides H, which are automatically or manually raised or lowered or moved sidewise, so as to open or close the ends of the said boxes or molds, the said slides 11 being down or closed when the pressing action is put on and raised or moved away for the discharging action to take place. The said slides H may be formed in the shape of wedges or otherwise.

For the purpose of manually opening and closing the ends of the molds or boxes A the slides H of the said molds or boxes A are joined to racks J and J, which gear with pinions K and'K. These pinions K and K normally gear with each other, and the pinion K" can be put in or out of gear with the rack J by'a clutch arrangement J the rack J being slightly smaller than the other one. This arrangement is shown in Figs. 1 to 3, and theautomatic arrangement is shown in Figs. 6 and 7. or shaft 13 has arms 13, joined to which are levers B and B thelatter being fulcrumed at B upon a bearing 13 securedto the table of the machine and joined to the slide H of Referring to these figures the axis.

the mold or box A. Upon the said axis or shaft-I3 are fixed couplings or clutches B with movable pieces B join ed by lever mechanism B to a hand-lever B pivoted at B to the machine-frame. The action is: hen the axis or shaft B is caused to turn by the action of the quadrant-wheel L, as hereinafter referred to, the levers B turn on their axes B and raise or lower the slides H, according to the direction in which the said quadrantwheel is moved. By means of the said handlever B the coupling-pieces B may be disengaged from the fixed couplings 13.

Referring again toFigs, 1 to 3, L is the quadrant-wheel, carried on the axis or shaft B (and having hand-pins L) and by which the machine is operated. On throwing over the quadrant-wheel L the toggle or its equivalent mechanism causes the presser-blocks B to give their pressing action through apertures in the sides of the mold or box A, the slides H having previously been closed by the handlever M or simultaneously through the auto matic apparatus described. After the pressing action has taken place the slides II are raised byhand through hand-lever M or automatically, as described under 6 and 7, and the quadrant-wheel reversed, so withdrawing the PIQSSGF'DIOCKS B.

By means of the shape of the mold A and the pressing action each brick is pressed to a uniform size and thickness and no arris is formed upon the brick. Theholes in the sides of the mold are smaller in area than the said sides of the mold and do not extend to either of its edges or corners, and the indentingplungers, which work in the said holes, bear directly against the clay. In consequence of this no ragged edge or arris is formed anywhere. on any side of the brick while being pressed in the mold, but a perfectly clean edge in lieu thereof, which in bonding or building looks and is much smarter than bricks as pressed or made heretofore.

The bricks, after being pressed, are discharged endwise of the molds by means (see Fig. 2), of the pusher-out N, which slides on a level with the bottom A of the mold or box A and is joined by link 0 to hand-lever P, pivoted at P to a bracket I upon the machine-frame. By operatingthe said handlever the pusher N is caused to pass through the mold or box A, so as to discharge the brick, and after such is easily and readily withdrawn.

In Figs. 4 and 5 the crank-shaftE is driven by pulleys E, one of which is fast and the other loose upon such shaft. The cranks C of said shaft E are joined to connecting-rods R, which are joined up to the links or toggle mechanism 1, to which the presser-blocks are connected. Rods U, carried by bearings V, are joined to the toggle mechanismT and have between them and the toggle. mechanism spiral springs orcushions for allowing for varying thicknesses of material. On operating the crank-shaft E the presser-blocks B, through the mechanism aforesaid, press the brick in the manner set forth with reference to Figs. 1 to 3; or the said molds or boxes A are provided with a movable top and solid ends or one solid end with small pusher-out in center and one loose end and a loose bottom or plate which is capable of being automatically raised for discharging the pressed article and lowered automatically after such discharge.

A cylinder or some similar arrangement carrying or provided with molds or boxes, as aforesaid, may be employed and rotated by hand automatically, so as to bring the said molds or boxes in turn between the said presser-blocks, so as to obtain the said pressing and delivery actions.

In some cases hinged doors with wheels, screws, weights, and loose plates may be employed in connection with the molds or boxes to close the ends.

A spring or cushion arrangement is provided in connection with the shafts operating the presser-blocks or in connection with the presser-blocks themselves, so as to compensate for varying thicknesses of material and to press all to one uniform thickness without arris.

The shafts or levers for operating the presser-blocks may be actuated by cams and runners or other suitable means.

The machine may be worked by hand or driven by power.

On comparing Figs. 10 and 11 with Figs. 8 and 9, the latter'o-f which show the old system and Figs. 10 and 11 our new system of pressing, it will be seen that no arris or deviation in the pressing, such as occurs by the system illustrated by Figs. 8 and 9, can occur by the use of our new system.

lVe would have it understood that although the presser-blocks are shown acting in the molds A in a horizontal direction the molds A may be arranged so that the presser-blocks may act in, a vertical direction.
